I am going to address you like the child you are with some questions .
Are you ready hambone ?
Let's start with some simple questions to see how smart you are
1 Can XRF determine the elemental composition of a german decal and also a subsequent match of an identical decal on another helmet ?
Sigh. You're trolling and IMHO, acting like a buffoon. We've been through all this and you do nothing but chase your tail and have insult tantrums when people here ask you to do more than carnival bark. All of this has been addressed and you've provided nothing substantive. You do seem to have limited your claims significantly now to just decals, presumably SS decals. However, even if we assume that you and your ray gun can come close to what you claim re the authentication of certain SS decals, your relative neophyte ignorance of the hobby fails to take into account the many sheets of original SS decals which were sold in the 60s-80s, by one guy. He would do the shows with them in a briefcase. This is well known, saw him and his briefcase myself. Where are those original decals now? They're on helmets of course. Bill Maertz, who has "restored" many a German helmet (he claims thousands of restorations) created many, perhaps hundreds, perhaps thousands, of SS helmets with original decals since the 70s. All the old school guys (which you ain't) know Maertz did this. Some of them had him "restore" SS helmets for them. Those helmets are now floating around as "original". Are these in your "database"? I saw a hilarious episode on a helmet forum where a fellow posted his high dollar "single decal SS" helmet that all gushed over. Maertz then posted that was one he "restored" and it was "original" because it was an original helmet mated with an original SS decal. That was a funny tantrum filled thread. That's why we were careful and skeptical even back then.
If you really had knowledge of the hobby, you'd also know that there were, and are, plenty of original M.40 no decal and M.42 no decal helmets which ended up with original SS decals on them and became "SS helmets" with the help of other "restorers". Are you shooting these with your ray gun? Are you using "baseline" helmets to establish your data from people selling them and assisting you? Finally, at this point is anyone with a brain stem and objective thinking capability supposed to trust your representations and methodologies? You are "objective"? This is about you and perhaps some others, Kelly Hicks perhaps, selling SS helmets and your ray gun services and COAs?
Look, I'll give you the last word. Then, I'm locking this thread because you're polluting it and being very repetitive and idiotic. If you or anyone else has an irrepressible urge to post something intelligent or, God forbid, you can come up with something substantive which supports your claims, PM me and I'll gladly open the thread and allow the post. However, at this point, IMHO, Maui, you are no further along than you were two years ago and your ranting is not even amusing as it was. So here you go, you get the last word to post conclusory gibberish and insults, which is the same as you've posted throughout this thread. When you, or Kelly Hicks, or anyone else who agrees with you (which at this point seems to be no one), can post something coherent, intelligent, and which actually supports your claims and is not carnival barking or moonbat squeaking, PM me and I'll gladly reopen the thread.
